isValidShortNumber() public method

Tests whether a short number matches a valid pattern. If a country calling code is shared by multiple regions, this returns true if it's valid in any of them. Note that this doesn't verify the number is actually in use, which is impossible to tell by just looking at the number itself. See {@link #isValidShortNumberForRegion(PhoneNumber, String)} for details.
public isValidShortNumber ( PhoneNumber $number ) : boolean
